1: c = 0.2. y * 0.6 = 6. 0.6 : x = 0.2. 3.7 * b = 0. b : 0.3 = 0.3.

Решение:

1. \( 1 : c = 0.2 \) \(\implies c = \frac{1}{0.2} = 5 \)
2. \( y \cdot 0.6 = 6 \) \(\implies y = \frac{6}{0.6} = 10 \)
3. \( 0.6 : x = 0.2 \) \(\implies x = \frac{0.6}{0.2} = 3 \)
4. \( 3.7 \cdot b = 0 \) \(\implies b = \frac{0}{3.7} = 0 \)
5. \( b : 0.3 = 0.3 \) \(\implies b = 0.3 \cdot 0.3 = 0.09 \)

Ответ: c = 5, y = 10, x = 3, b = 0, b = 0.09.
